The wierd guy at a dance/night club who sits on the sidelines, Alone, until he has enough alcohol in him to randomly grind on anyone and every woman in site on the Dance floor. He creeps up without warning and before you know it, he is grinding on your ass without even a Hello. This guy also seems to never ever go away!

I was dancing when a Dance Club Creeper took it upon himself to sneak attack me with his thrusting grind moves on my behind...I then spent the rest of the night dodging him like Roadrunner
